TH3731U - Window or door frame locking device - Google Patents

Abstract

The DC60 window or door frame locking device consists of a mounting part that attaches to the outer support base. The front of this base has a recessed groove, while the back has a raised section that slides into the inner recessed groove of the window or door frame. Another section of the outer support base has a side edge to act as a shoulder when the sliding locking part is attached to the outer support base. The sliding locking part consists of a sliding support base with a bent upper end to receive the force required to lock or unlock the window or door frame. A raised support plate is located above the sliding support base for the locking/unlocking plate, which is then secured to the locking/unlocking plate slot on the opposite side of the window or door frame. The underside of the locking/unlocking plate has alternating serrations to accommodate the alternating serrations on the upper side of the sliding push bar. The upper sliding push bar has alternating serrations on its top to accommodate the alternating serrations on the lower side of the locking/unlocking plate. The bottom of the upper sliding push bar also serves as a spring support. The mounting mechanism consists of a top end support for the push spring rod, and the other end of the push spring rod is attached to the top of the bottom sliding push rod. The bottom sliding push rod has a hole that goes through it to accommodate the insertion of the lower support tube for mounting to the frame. The top of the bottom sliding push rod serves as a lower spring support rod to accommodate the insertion of the other end of the push spring rod. The window or door frame locking device consists of a mounting part that attaches to the frame, which is an outer support base. The front side has a recessed groove, and a portion of the back side is raised to fit into the inner recessed groove of the window or door frame. Another part of the back of the outer support base has a side edge to act as a side shoulder when the sliding lock is attached to the outer support base. The sliding lock consists of a sliding support base, the top end of which is folded upwards to receive the force for locking or unlocking the window or door frame. There is also a raised support plate that protrudes from the sliding support base for placing over and securing the locking/unlocking plate. This locking mechanism is used to engage the locking slot of the opposite side of the window or door frame. The underside of the locking plate has alternating serrated teeth to accommodate the alternating serrated teeth on the upper side of the upper push-pull bar. The upper push-pull bar has alternating serrated teeth on top to interlock with the alternating serrated teeth on the bottom of the locking plate. The bottom of the upper push-pull bar has an upper spring support bar to accommodate the upper end of the spring bar. The other end of the spring bar is fitted onto the top of the lower push-pull bar, which has a hole through it to accommodate the insertion of the lower mounting tube for attachment to the frame. The top of the lower push-pull bar has a lower spring support bar to accommodate the other end of the spring bar.
